TONGUE FOR MOWERS AND REAPERS.

SPECIFICATION forming part of Letters Patent No. 364,581, dated June '7, 1887.

ApplieatiorffilcdFebruary15,1887. SerialNo.2-27,753. (No model.)

- Maryland, have invented certain new and useful Improvements in Tongues for Reapers and Mowers, of which the following is a specification.

The object of this invention is to afford a simple and easy mode of adjusting the tongue of harvesting and mowing machines without detaching the same, whereby it is adapted todraw the machine along hillsides of varying declivity in a direct line with greater ease and regularity of path.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a plan view of the tongue and 1 my improved connection with a harvester.

Fig. 2 is a side viewof' part of the improved tongue shown in Fig. 1. Fig. 3 is a plan view of the tongue and a modification of the connection with a harvester. Fig. 4 is a side view of part of the improved tongue shown in Fig.

3. Fig. 5 is a sectional detail of the adjusting device seen in Fig. 3.

It is unnecessary to show or describe an entire harvestingmaehine, as my improvement may be used or attached to any of the ordinary or well-known machines.

Theletter A designates a wheel, B the frame, and G the finger-bar, of a machine. The tongue or pole D has two movements-to wit, an upand-down movement and a lateral movement to both the right and left. The up-and-down movement is effected, in the usual way, by having the end of the tongue pivoted to the machine-frame at e, and provisionis made for the lateral movement to both right and left of a central position. Referring to Fig. 1, it will be seen that the lateral movementis effected by providing the end of the tongue with a flat plate-spring, f, which has at one end the pivoteye 6, the broad side of the plate-spring being in a vertical plane, and thus arranged the tongue from the pivot eye 6 forward is stiff, vertically considered, but is flexible, horizontally conside'red,'and its free end as may be moved from the central position which it occupies either to the right or left, as indicated by broken lines. The tongue is shifted laterally more "or less, as may be desired, by a to the tongue.

movable braeebar, G. Several constructions may be made use of to afford the necessary movement of the l)race-bar. In Fig. 1 a screwrod, H, extends in the same direction as the axis of the tongue-pivot at c. This serew-rod is squared at one end, i, and may be turned in its bearings j without advancing. A screwnut, is, is on the rod H, and one end of the brace-bar G is connected with said screw-nut by a pivot, Z. The other end of the brace-bar is eonnectedwith the tongue by a pivot, m. In order to move the brace-bar, and thereby shift the free end of the tongue laterally, it is only necessary to turn the screw-rod H, which is done by applying a wrench to its square end i. Turning the screw rod has the effect of moving the serew-nut7r, and with it one end of the brace-bar.

In the present instance, Fig. 1, instead of the brace -bar being directly pivoted to the tongue, it is pivoted to a nut, 'It, on a screwbolt, 0, turning freely in bearings 19, secured By this last-described device, in addition to the screw-rod H and nut 70, the brace-bar may have both of its ends moved.

Referring to Figs. 3, 4., and 5, it will be seen that the lateral movement of the free end at of the tongue is effected by a joint, q, at the tongue end, which couples with the pivot-eye part c. In this case there are two pivots, each turning in a different plane.

I do not claim, broadly, a tonguehaving two pivots turning in different planes, so as to permit the tongue to have two movements, as that has been done before for the purpose of putting the tongue at right angles to its ordinary positionthat is, turning it through an arc of not less than ninety degrees-so as to allow of drawing the machine on truck-wheels for transportation from place to place. My device does not permit a lateral movement to the extent named, nor is it designed for the same purpose. On the other hand, the device re-- ferred to is not adapted for adjusting the tongue laterally to both right and left of a central position, as mine is, nor to be shifted laterally more or less, so as tosuit the declivity of hillsides. The end of the brace-bar G in this lastnamed construction is jointed to a collar, 1, loosely surrounding the screw nut which has a square or hexagonal face, 8, for the grip of a wrench. This nut travels on a rack-bar,

ICO

I-l, which is fixed rigidly to the machine. Turning the nut It will shift the free end of the tongue. The nut k is screw-threaded; so also is the rod H. The brace-bar Gwill be moved in one case by turning the screwnut, and in the other by turning the screw-rod. A screw, therefore, in either case moves the brace-bar.

It will be seen that in the combination here described the pivot-eye e and tongue may have combined with them either one of the two lateral-movement devices-that is to say, the springf or thejoint q may be interposed between the tongue proper and the pivot-eye e, said devices being equivalents in the combiuation.

\Vhen it is desired to draw the machine on a hillside with the end i of the finger bar 0 pointing up the hill, the tongue D should be shifted to the right of the central position; and when it is desired to draw the machine along a hillside with the end of the cutterbar pointing down thehill, the tongue should be shifted to the left of the central position. The extent of the tougues deviation from the central position will be governed by the steepness of the hillside. By thus adjusting the tongue later ally the machine may be drawn in a direct or regular path and the difficulties avoided that result in attempting to draw the machine on hillsides while the tongue is inthe ordinary central position.

Having described my invention, I claim and desire to secure by Letters Patentof the United States- 1. In a harvesting-machine, the combination of the frame B, provided with the finger-bar O, a tongue, D, connected with the said frame by a pivot-eye,whercby its free end may have an up-anddown movement, aspring or equivalent means interposed between the tongue proper and said pivot-eye, whereby the free end of the tongue may move both to the right and left of a central position, a movable bracebar pivoted at both ends to stay the tongue, and a screw to move one end of the said bracebar, whereby to shift the tongue laterally more or less.

2. In aharvesting-machine, the combination of the frame B, the tongue D, pivoted at 0, so that it may have an up-and-down movement, and provided with a spring, f, to permit of a lateral movement to both right and left of a central position, a rod, H, attached to the frame and extending in the same plane and direction as the axis of the said pivot at c, a bracebar, G, connecting the frame and tongue, and having the pivots Zmat the rear and front. respectively, and one end movably connected with the said rod, as set forth.

In testimony whereof I affix mysignature in the presence of two witnesses.
